Bad Service

My ADSL is not working. I have logged a call, according to the online app an appointment was made for 13/02/2019 however nobody arrived. When phoning the call center @ around 16:00 they just said the technician is still busy. Today the date on the app for the appointment was move to today's date, however when phoning at around13:30 they still could not tell me what is happening and when somebody will be dispatched. The call center agent did the same test as done the day we logged the call to no satisfaction. This is unacceptable to sit without a service that I have to pay for. The call center agents are not very helpful and not interested in referring you to a supervisor or team leader.
